Investigation of kinetics models and equilibrium isotherms for congo red dye adsorption on activated carbon prepared from fruits industry wastes

Abstract : Dye effluents resulted from various industries are noxious both for the environment and for living beings. Therefore, contaminated wastewaters rise important concerns and require adequate treatment methodologies. In the last years, many procedures going from the advanced oxidation processes to the retention on different materials possessing adsorption properties were developed and applied for removing persistent dyes. Sorption of Congo Red dye was investigated in this paper. In the studied conditions, the adsorbent material prepared from cherry stones by physical activation through calcination was able to remove more than 90% of the targeted pollutant. Data fitted with high accuracy (correlation coefficient superior of 0.99) the pseudo-second-order kinetics and Freundlich isotherm model. © 2019 IEEE.
